Description

Technical Field

[0001] The present invention belongs to the technical field of anti-corrosion coating preparation, and in particular relates to a device and a method for preparing an adaptive anti-corrosion coating for a metal anchor rod in a humid environment. Background Art

[0002] Metal anchor rods are a key component widely used in geotechnical engineering, mining, tunnel construction and other fields. They play an important role in reinforcing rock mass and stabilizing structure. In actual use environment, especially in humid environment, metal anchor rods are very susceptible to corrosion. Corrosion will not only weaken the mechanical properties of metal anchor rods, resulting in a decrease in their bearing capacity, but may also cause structural safety hazards, seriously threatening the stability and safety of the project.

[0003] At present, in order to effectively extend the service life of metal anchors and ensure the long-term stable operation of the project, the preparation of adaptive anti-corrosion coatings has become a key measure. Since the adaptive anti-corrosion coating can form a dense protective barrier on the surface of the metal anchor, it blocks the direct contact between the external corrosive medium and the metal anchor, thereby slowing down or even preventing the occurrence of corrosion;

[0004] However, in the existing equipment for preparing anti-corrosion coatings for metal anchor rods, common stirring devices mostly rely on fixed-shaped stirring components, such as a single stirring blade, and its stirring range and strength are difficult to achieve comprehensive, in-depth and sufficient stirring, which ultimately leads to uneven mixing of the coating raw materials. In actual applications, the unevenly mixed coating is very likely to have inconsistent protective performance, seriously affecting the anti-corrosion effect of the metal anchor rod. In view of the above technical problems, it is necessary to provide an equipment and method for preparing adaptive anti-corrosion coatings for metal anchor rods in a humid environment.

[0016] A method for preparing an adaptive anti-corrosion coating preparation device, comprising the following steps:

[0017] Step 1: When using, first add the coating raw materials into the mixing tank in proportion. The solid raw materials can be added first, and the liquid raw materials can be added in time according to the process requirements;

[0018] Step 2: After the raw materials are filled, the elastic rod and the counterweight block on the rotating shaft are driven to rotate so as to stir and mix the raw materials;

[0019] Step 3: When the rotating shaft rotates, the counterweight is acted upon by centrifugal force. When the rotating speed is faster, the centrifugal force increases and the elastic rod extends outward. When the rotating speed is slower, the centrifugal force decreases and the elastic rod contracts, so that the stirring range and strength are continuously changed in the mixing tank.

[0020] Step 4: During the mixing of the raw materials, an external air source supplies air into the air delivery cavity, and finally the air is quickly ejected through the air jet hole on the counterweight block, so that the air impacts the coating raw materials in the mixing tank;

[0021] Step 5: Due to the change of centrifugal force of the counterweight, the elastic rod will stretch and contract to different degrees, so that the air jet holes will spray gas in different areas of the mixing tank;

[0022] Step 6: When the rotating shaft rotates, the connecting shaft that rotates synchronously with the rotating shaft can move back and forth regularly in the installation cavity. When the connecting shaft rises, the connecting area between the gas delivery port and the gas delivery cavity will gradually increase, so that the gas source can enter the gas delivery cavity more smoothly and in large quantities, and finally be ejected from the gas injection hole;

[0023] Step 7: When the connecting shaft is raised or lowered, the rack drives the gear ring to rotate, thereby driving the elastic rod and the counterweight block at its end to rotate, so that the raw material is disturbed from different angles;

[0024] Step 8. After the coating is prepared, the uniformly mixed coating raw materials are discharged from the mixing tank, and then the coating raw materials are coated on the metal anchor rod with the help of coating equipment.

[0025] Compared with the prior art, the adaptive anti-corrosion coating preparation equipment for metal anchor rods in a humid environment of the present invention changes the extension degree of the elastic rod by using the centrifugal force of the counterweight block, continuously adjusts the stirring range and strength, and fully and evenly mixes the coating raw materials. At the same time, the booster pump delivers gas and sprays it through the jet hole to enhance the impact force and stirring effect on the raw materials, so that the coating raw materials are mixed more evenly.

[0026] By utilizing the lifting and lowering of the connecting shaft to control the gas ejection amount, and driving the elastic rod and the counterweight block to rotate at the same time, the raw materials are disturbed from multiple angles. This all-round, multi-level stirring method enables the raw materials to be more fully contacted and integrated during the mixing process, greatly improving the mixing uniformity, greatly shortening the mixing time, and improving production efficiency.

DETAILED DESCRIPTION

[0041] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0042] Example 1: Reference Figure 1 , Figure 3 , Figure 5 , Figure 6 , a self-adaptive anti-corrosion coating preparation device for metal anchor rods in a humid environment, comprising a mixing tank 1, the top and side walls of the mixing tank 1 are fixedly connected with a feeding pipe, and also comprising: a rotating shaft 3 rotatably connected in the mixing tank 1, wherein a plurality of groups of elastic rods 301 are equidistantly rotatably connected to the rotating shaft 3, each group of elastic rods 301 is provided with a plurality of elastic rods, and are equidistantly distributed along the outer wall of the rotating shaft 3, and an installation cavity 4 is opened in the rotating shaft 3; a connecting shaft 401 is lifted and connected in the installation cavity 4, and rotates synchronously with the rotating shaft 3; a counterweight block 302 is fixedly installed on the end of the elastic rod 301 away from the rotating shaft 3, wherein the connecting shaft 401 A hollow cavity 402 is provided inside, an air delivery cavity 403 is provided inside the counterweight block 302 and the elastic rod 301, a gas delivery port 405 connected to the gas delivery cavity 403 is provided on the connecting shaft 401, the gas delivery cavity 403 is connected to the hollow cavity 402 through the gas delivery port 405, an air injection hole 404 connected to the gas delivery cavity 403 is provided on the counterweight block 302, the gas delivery port 405 is arranged in a trapezoidal shape, the opening width of the lower end of the gas delivery port 405 is the same as the outer diameter of the gas delivery cavity 403, the opening width of the upper end and the opening width of the lower end are gradually reduced, and the hollow cavity 402 is used for connecting an external gas source to supply gas to the gas delivery cavity 403.

[0043] A booster pump 406 is fixedly installed on the outer wall of the mixing tank 1, and an air pipe 407 is fixedly connected to the output end of the booster pump 406. The end of the air pipe 407 away from the booster pump 406 is connected to the hollow cavity 402 through a rotary joint 408, and the rotary joint 408 is arranged on the upper end of the connecting shaft 401.

[0044] A motor 303 is fixedly mounted on the mixing tank 1 , a gear 1 304 is fixedly mounted on the output end of the motor 303 , and a gear 2 305 meshingly connected with the gear 1 304 is fixedly mounted on one end of the rotating shaft 3 penetrating the mixing tank 1 .

[0045] The bottom of the mixing tank 1 is fixedly connected with a discharge pipe 101 , and a valve switch is arranged on the discharge pipe 101 .

[0046] When in use, firstly, coating raw materials are added into the mixing tank 1 in proportion through the feeding pipe. Solid raw materials can be added first, and liquid raw materials are added in time according to process requirements. Then, the motor 303 is started. The motor 303 drives the rotating shaft 3 to rotate through the meshing connection of the gear 1 304 and the gear 2 305. When the rotating shaft 3 rotates, the elastic rod 301 and the counterweight block 302 thereon rotate accordingly, so that the raw materials are stirred and mixed.

[0047] At the same time, when the rotating shaft 3 rotates, the counterweight 302 is acted upon by the centrifugal force. When the rotating speed is fast, the centrifugal force increases, and the elastic rod 301 extends outward. When the rotating speed is slow, the centrifugal force decreases, and the elastic rod 301 contracts, so that the stirring range and strength are constantly changed in the mixing tank 1, so that the coating raw materials in the mixing tank 1 can be fully and evenly mixed.

[0048] During the mixing of the raw materials, the booster pump 406 is started, and the booster pump 406 delivers gas to the hollow cavity 402 through the gas delivery pipe 407, and then delivers the gas in the hollow cavity 402, and then delivers the gas into the gas delivery cavity 403 through the gas delivery port 405, and finally quickly ejects the gas through the jet hole 404 on the counterweight block 302, thereby enhancing the impact force and stirring effect on the raw materials;

[0049] At the same time, as the rotating shaft 3 rotates, the elastic rods 301 at different positions will expand and contract to different degrees due to the change of the centrifugal force of the counterweight block 302, so that the gas injection holes 404 spray gas in different areas of the mixing tank 1 to stir the raw materials, so that the coating raw materials are mixed more evenly;

[0050] When the coating is prepared, open the valve switch on the discharge pipe 101 at the bottom of the mixing tank 1, and use gravity to make the evenly mixed coating flow out along the discharge pipe 101, so as to achieve smooth collection of the finished product and provide convenience for subsequent anchor rod coating.

[0051] Example 2: Reference Figure 1 , Figure 2 , Figure 5 , Figure 7 , Fig. 9 , Fig.10 , Fig.11 , a device for preparing an adaptive anti-corrosion coating for a metal anchor in a humid environment, which is basically the same as Example 1, and further, a limiting sleeve 501 is sleeved on the connecting shaft 401, and the inner wall of the limiting sleeve 501 is equidistantly provided with lifting and lowering grooves 502 with undulating heights, and sliders 503 are symmetrically fixedly installed on the connecting shaft 401, and the sliders 503 are slidably connected in the lifting and lowering grooves 502, and the limiting sleeve 501 is fixedly installed on the mixing tank 1, and a guide groove 5 is opened on the connecting shaft 401, and a guide block is fixedly installed on the rotating shaft 3, and the guide block is slidably connected in the guide groove 5.

[0052] A gear ring 601 is fixedly installed on one end of the elastic rod 301 passing through the installation cavity 4. A rack 6 is arranged in the installation cavity 4. The upper end of the rack 6 is fixedly installed on the outer wall near the upper end of the connecting shaft 401. The gear ring 601 is meshed and connected with the rack 6.

[0053] When the rotating shaft 3 rotates, the connecting shaft 401 rotates synchronously with the rotating shaft 3 under the cooperation of the guide block and the guide slot 5. When the connecting shaft 401 rotates, its own slider 503 performs regular reciprocating lifting and lowering motion in the lifting and lowering slot 502 with undulating inner walls of the limiting sleeve 501, so that the connecting shaft 401 can achieve stable and controllable lifting and lowering in the installation cavity 4.

[0054] When the connecting shaft 401 rises, the communicating area between the gas delivery port 405 and the gas delivery cavity 403 will gradually increase, which is like opening the "valve" of the gas channel, so that the gas from the gas source through the hollow cavity 402 can enter the gas delivery cavity 403 more smoothly and in large quantities, and finally be ejected from the gas injection hole 404, which greatly increases the gas ejection amount. When the connecting shaft 401 descends, the communicating area between the gas delivery port 405 and the gas delivery cavity 403 will gradually decrease, and the gas ejection amount will decrease accordingly, further disturbing the raw materials, so that the coating raw materials can be mixed more fully and evenly in the mixing tank 1;

[0055] At the same time, during the lifting process of the connecting shaft 401, the rack 6 fixedly installed on the outer wall thereof also moves synchronously. When the connecting shaft 401 is lifted or lowered, the rack 6 drives the gear ring 601 to rotate, thereby driving the elastic rod 301 and the counterweight block 302 at its end to rotate. This rotation and the movement of the elastic rod 301 caused by the change of the centrifugal force of the counterweight block 302 are superimposed on each other, disturbing the raw materials from different dimensions and methods, greatly shortening the time required for mixing and improving production efficiency.

[0056] In summary, by controlling the gas ejection amount by lifting and lowering the connecting shaft 401, and driving the elastic rod 301 and the counterweight block 302 to rotate, the raw materials are disturbed from multiple angles, so that this all-round and multi-level stirring method enables the raw materials to be more fully contacted and fused during the mixing process, greatly improving the mixing uniformity.

[0057] It should be noted that one end of the elastic rod 301 penetrating the installation cavity 4 is made of a hard material. Therefore, when the connecting shaft 401 is raised or lowered, the gear ring 601 can be driven to rotate stably by driving the rack 6 .

[0058] Example 3: Reference Figure 1 , Figure 4 , a self-adaptive anti-corrosion coating preparation device for metal anchor rods in a humid environment, which is basically the same as Example 1, and further, a receiving plate 2 is sleeved on the rotating shaft 3, the receiving plate 2 is fixedly installed in the mixing tank 1, and is located above the feeding pipe on the side wall of the mixing tank 1, and a grinding groove 201 is provided on the receiving plate 2, and the grinding groove 201 is arranged in an annular shape, and a blanking hole connected to the grinding groove 201 is provided on the receiving plate 2, and a grinding ball 203 is arranged in the grinding groove 201, and the grinding ball 203 is fixedly connected to the rotating shaft 3 through a connecting rod 202;

[0059] When using the metal anchor rod adaptive anti-corrosion coating preparation device, firstly, solid raw materials are added from the main material pipe at the top of the mixing tank 1. Due to the effect of gravity, the solid raw materials will fall into the grinding groove 201 on the receiving plate 2 located in the mixing tank 1;

[0060] At the same time, as the rotating shaft 3 rotates, the grinding balls 203 rigidly connected to the rotating shaft 3 through the connecting rod 202 move accordingly. At this time, the grinding balls 203 continuously squeeze and rub the solid raw materials by their own weight and the centrifugal force brought by the rotation, so that the solid raw materials are gradually ground into fine powder.

[0061] At the same time, during the grinding process, since there are drop holes evenly distributed at the bottom of the grinding tank 201, the raw materials ground into powder can fall evenly into the bottom of the mixing tank 1 through the drop holes under the synergistic effect of multiple factors such as their own gravity, slight vibrations caused by the rolling of the grinding balls 203, and airflow disturbances caused by the rotation of the rotating shaft 3, and mix with the liquid raw materials pre-added into the mixing tank 1. This uniform falling method avoids the solid raw materials from directly entering the liquid raw materials in the form of large agglomerates, resulting in uneven mixing, prolonging the mixing time, and possibly forming areas with excessively high or low concentrations locally, affecting the final performance of the coating. By grinding into powder and dropping it evenly, the solid powder can be quickly and evenly dispersed in the liquid raw material, greatly improving the initial uniformity of the solid-liquid mixing, and creating favorable conditions for further mixing in the mixing tank 1 and preparing high-quality metal anchor anti-corrosion coatings.

[0062] The upper end of the receiving plate 2 is inclined toward the grinding groove 201;

[0063] When the raw materials are added to the receiving plate 2 from the feeding pipe, due to the existence of the inclined surface, the raw materials will naturally slide towards the grinding groove 201 under the action of their own gravity. At the same time, when the rotating shaft 3 drives the grinding balls 203 to grind the raw materials in the grinding groove 201, the vibrations and air flow disturbances generated may cause some of the ground or unground raw materials to splash and scatter outward. The inclined upper end surface of the receiving plate 2 can use gravity to guide these possibly scattered raw materials back into the grinding groove 201, ensuring that the raw materials are always in the area where they are effectively processed, thereby improving the utilization rate of the raw materials and reducing waste.

[0064] Example 4: Reference Figure 4 , Figure 6 , Figure 8, a self-adaptive anti-corrosion coating preparation device for metal anchor rods in a humid environment, which is basically the same as Example 1, and further, a support plate is fixedly connected to the rotating shaft 3, a plurality of sleeves 204 are equidistantly arranged on the support plate, a knocking rod 205 is slidably connected in the sleeve 204, a spring 206 is arranged in the sleeve 204, one end of the spring 206 is fixedly connected to the knocking rod 205, and the other end is fixedly connected to the inner wall of the sleeve 204, and a plurality of push blocks 207 corresponding to the knocking rod 205 are fixedly installed equidistantly in the circumference of the lower end surface of the receiving plate 2;

[0065] As the rotating shaft 3 rotates, the supporting plate drives the sleeve 204 and the knocking rod 205 to rotate together. When the knocking rod 205 encounters the pushing block 207 on the lower end surface of the receiving plate 2, the pushing block 207 pushes the knocking rod 205 to overcome the elastic force of the spring 206 and retract into the sleeve 204. When the knocking rod 205 passes over the pushing block 207, the spring 206 rebounds, pushing the knocking rod 205 to knock the receiving plate 2, causing the receiving plate 2 to vibrate. The raw material particles collide and rub against each other under the action of the vibration, so that the raw materials that were originally agglomerated are broken up, which effectively promotes the loosening of the raw materials, puts them in a good dispersed state, and avoids agglomeration.

[0066] Among them, the vibration of the receiving plate 2 is transmitted to the inner wall of the grinding groove 201, so that the raw material particles that may adhere to the inner wall fall off under the vibration, preventing the raw material from adhering and accumulating for a long time and blocking the blanking port, thereby ensuring the smoothness of the blanking process. At the same time, since the raw material is always in a loose and flowing state, the grinding ball 203 can more fully contact the raw material when rolling and grinding the raw material under the drive of the rotating shaft 3, avoiding the problem of uneven or insufficient grinding due to raw material agglomeration and adhesion, thereby improving the grinding effect of the grinding ball 203 on the solid raw material.

[0067] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention.

10. A method for preparing the adaptive anti-corrosion coating preparation device according to claim 5, characterized in that: Use the following steps: Step 1: When using, first add the coating raw materials into the mixing tank in proportion. The solid raw materials can be added first, and the liquid raw materials can be added in time according to the process requirements; Step 2: After the raw materials are filled, the elastic rod and the counterweight block on the rotating shaft are driven to rotate so as to stir and mix the raw materials; Step 3: When the rotating shaft rotates, the counterweight is acted upon by centrifugal force. When the rotating speed is faster, the centrifugal force increases and the elastic rod extends outward. When the rotating speed is slower, the centrifugal force decreases and the elastic rod contracts, so that the stirring range and strength are continuously changed in the mixing tank. Step 4: During the mixing of the raw materials, an external air source supplies air into the air delivery cavity, and finally the air is quickly ejected through the air jet hole on the counterweight block, so that the air impacts the coating raw materials in the mixing tank; Step 5: Due to the change of centrifugal force of the counterweight, the elastic rod will stretch and contract to different degrees, so that the air jet holes will spray gas in different areas of the mixing tank; Step 6: When the rotating shaft rotates, the connecting shaft that rotates synchronously with the rotating shaft can move back and forth regularly in the installation cavity. When the connecting shaft rises, the connecting area between the gas delivery port and the gas delivery cavity will gradually increase, so that the gas source can enter the gas delivery cavity more smoothly and in large quantities, and finally be ejected from the gas injection hole; Step 7: When the connecting shaft is raised or lowered, the rack drives the gear ring to rotate, thereby driving the elastic rod and the counterweight block at its end to rotate, so that the raw material is disturbed from different angles; Step 8. After the coating is prepared, the uniformly mixed coating raw materials are discharged from the mixing tank, and then the coating raw materials are coated on the metal anchor rod with the help of coating equipment.
